HI there, quick question for all of you...How do I know when I have entered into Ketosis?

Bad news? There is no reliable way to know for sure.

Good news? It doesn't matter. Follow the protocol and it works.

John is right, just follow the protocol and you will be fine.
I've been on the program for 9 weeks and have lost 30lbs - I've tried the ketostix throughout and they have always shown that I am not in ketosis...it doesn't bother me, because I know I am (the weight loss and the stinky breath proves it!).
My coach said not to worry about the ketostix as much as staying on protocol.

I hope this helps. This diet does work, just be patient and let your body do its thing.
